Y Improvements in Glass-Shearing Devices, whereof the following is a specification, reference being had to the accompanying drawings.

It is the object oi my invention to provide `an attachment ior a glass forming machine, adapted to automatically shear molten glass and supply the same to a mold or molds comprised in said machine.

The ioriu oi my invention hereinafter described comprises a ironie adapted to be secured in stationary relation with the glass forming machine, and a shearing slide plate mounted to reciprocate in said irarne in such relation with the operation oi said glass forming machine as to shear and deposit the glass in proper relation with the molds utilized in said machine Hy invention comprehends the various novel features ci' construction and arrangement hereinafter more definitely speciiied and claimed.

In the accompanying drawings, Figure I, is a plan view/showing a convenient embodiment o my invention. Fig. ll, is an elevation of the left hand side of` the device, shown in Fig. I. Fig. III, is a sectional view taken on the line III, III, in Figs. I and II.

In said ligures, l, is the frame which is conveniently provided with the arm 2, for stationary engagementwith the standard ot' the glass forming machine, to which said frame is thus secured so that the guide plate e, has its opening 5, in concentric relation with mold 6, supported by the member 7, of said ma chine. Said i'rame l, is provided at its Aopposite end with brackets 8, which support the rock shaft 9, which is provided with the arm Il, which may be conveniently connected by the rod l2, so as to be operated in delinite relation to the operation of said glass forming i machine. Said sha-it 9, is provided with the arm 15, between said brackets 8, which is connected by the linkl, with the boss 15,0111 the shearing slide plate 19, which is arranged to reciprocate in said raine l, being retained therein by the opposite overhanging edges oi said iranie, as indicated in Fig. III. Said plate I9, carries the bushing 2l, comprising the truncated conical receptacle 22, so as to sweep its upper shear edge 23, beneath and in shearing relation with the stationary shear blade 25, which overhangs said plate I9, and is adjust-ably supported in. stationary relation therewith by the bolt 27, extending from the' standard 28, through the slot 29, in the shank 30, of said blade.

As indicated in Fig. III, the slide I9, is preferably chambered, as indicated at 32, so as to receive a cooling medium which may be conveniently directed therethrough by the inlet B3, and outlet 34. It is. to be understood that said inlet andy outlet may be connected by iiexible tubes with asupply oi cooling medium, ior instance, Water.

The device'above described, operates as followsa-A gather oi' glass is lowered into the receptacle 22, and the slide 19, is shifted in the direction of the arrow marked thereon in Fig. I, so as to carry the bushing 21, past the blade 25, so as to shear from the gather by the co-operation of the shear edge 23, oi the bushing and the blade 25, suficient glass to charge the receptacle 22, the gather being supported during the operation by said blade 25. Further traverse oi the slideplate I9, presents said bushing 2l, in registry with the opening 5, in said guideplate 4, so that the charge oi glass is dropped from vthe receptacle 22, into the'rnold 6, which mold is thereupon shifted to the position where it may be subjected to the pressing operation.

I do not desire to limit myself to the precise details of 'construction and arrangement herein set forth, as'it is obvious that various modifications may be made therein, without departing from the essential features of my invention.

1. In u glass shearing device, the combination with a reciprocatory slide plate, having a glass receptacle` opening therethrough; of a frame comprising slideways engaging said plate; a stationary shearing blade overhanging said plate in operative relation therewith; and, means arranged to reciprocate said plate in said frame, comprising a rock shaft; zi lever arm; and, a link connecting said lever arni with said plate, substantially as set forth.

2. ln aglass shearing device, the combination with a reciprocatory ,slide plate, having a glass receptacle opening therethrough; of a frame comprising slideways engaging said plate; a stationary shearing blade overhanging said plate in operative-relation therewith; and, means adjustably connecting said 'blade with said frame, comprising a shank on said blade provided with a slot; and a holt entered through said slot, substantially :is set forth.

3. ln a glass shearing device, the combination with a stationary frame; ot' a shearing slide plate arranged to reciprocate in said frame a glass receptacle in said plate having a shearing edge at the top thereof; a stationary blade supported by said frame, overhanging said .plate in cooperative relation with said shearing edge; and, means whereby said pluie is presented with the glass receptacle remote from said blade to receive the glass, and then rel ciprocuted in coperative relation with said blade to shear the glass, substantially set forth.

in a glass shearing device, the combination with a stationary traine; of a shearing slide plate arranged to reciprocate in said frame; u bushing in said plate, compris ing a truncated conical receptacle having a shearing edge at its top; .1 shear blade above said plate; and, means whereby said plate is reciprocated in cooperative relation with said shear blade, substantially as set forth.

5. ln :x glass shearing device, the combination with a stationnrl trame; of a shearing slide plate arranged to rei eiprocate in said frame; a bushing in said plate, comprising a truncated conical receptacle having a shearing edge at its top; and a chamber in said plate surrounding said bushing; means to direct a cooling medium through said chamber: a shear blade above said plate; and, means whereby said plate is recprocated in coperativerelation with said shear blade, .substantially as set forth. v

In testimony whereof, I have hereunto signed my nam 1() at Philadelphia, Pennsylvania, this lirst day of Decemljer 1905.
